Re: The monsters wakes up ! Katla Hekla Iceland Dead Zone and rift as uniform system ! A lot of others worldwide !

When I see an upward spiral of smoke/cloud then I get interested. This looks as though it's a cloud, not an eruption. Another view from a different webcam: [link to www.ruv.is] Also another webcam for katla: [link to www.ruv.is]

only clouds...

Now at it so, but look again more attentively at an initial picture [link to i43.tinypic.com] the sky is crystal clear so is inclined to think that small short-term emission of ashes all the same was.

But thanks for the reminder to check the Iceland webcams.

Thanks you! Unfortunately 1st link now -too shiny, 2nd not working for me(

GeoLoco says:February 18, 2012 at 17:36Wasn’t 1814/15 the year without a summer? Origin from another beast…Only a detail.Great update on the situation. Faster than any press could be.Journalists: seriously, there’s time before to panic…

Carl le Strange says:February 18, 2012 at 17:36As far as I know nothing like this has ever been recorded.Even if it is most likely to small to become anything at this stage, it is enough to make me jump… The Dead Zone, never has activity like this, never!

It contains a 10 x 8 km caldera.In 1724, Krafla began an eruption that lasted for five years. This eruption was called "The Myvatn Fires." It was named for the nearby area of Myvatn, which is a rich farming district and very well populated. During this eruption, lava flowed from a ~7 mile (11 km) long fissure until it reached ~12.5 miles (20 km) in length after one year [link to volcano.oregonstate.edu]

"Please dear all, it is still far from any possible eruption in the area. At most this is a signal of what can come, nothing more.

CARL"

But then, few hours later:

"Sam says:February 18, 2012 at 17:57Hi Carl and Others, Just a question:

How much activity i.e: Harmonic Tremoring, Earthquakes etc… Would be required before we should worry? ReplyCarl le Strange says:February 18, 2012 at 17:58Probably more than this.But since this is unchartered territory nobody really knows how much “more than this” is required. In a way anything new is a bit worrying"

Nothing to see here, move along...:)

Seriously, though; the weather here changes drastically on average every half-hour, with the recent changes in the weather pattern (post gulf-oil bleah bleah), things have become less drastic, but otherwise, unless the red glowing stuff is at your doorstep, there's no reason to panic...

At the moment we're swinging from ice-covered winter to early summer-type surroundings, backa nd forth, for the past month it's been crazy; but we jave seen worse in living memory...

Ok i'm happy with that, but my dear icelander friend, as you know things can chage very fast to iceland volcanos, and this activity in Dead zone it's not a good sign... stay safe!

I always said that the people in a literal sense living on volcanoes is a special breed, heroic people and that they were excited with something, something is necessary really fasntastic extraordinary :)))

[link to volcanocafe.wordpress.com] About Hekla tremor [link to hraun.vedur.is] "Carl le Strange says:February 20, 2012 at 10:18There is no tremor at Mjoaskard.I wrote a short note on it yesterday in the comments.Those are microceisms that happen between 2 and 10 minutes apart. And because of every stapel on the plot (1 pixel wide) is 28m 48s in time, you get several microseisms in one stapel (st&#228;bchen). That makes it look like tremor, but it is not. The actual tremor level on the plot is quite low really.

These microseisms are a bit odd. I do not know if they are icequakes or popcorn. That is impossible to tell since I do not have depth.

SNB also is having microceisms (most likely frost quakes), not harmonic tremoring.

And for those wondering, yes, I do see the microceisms one at a time."

Hmm. Means, it not a tremor - but that this such ideas aren't present.Let's look that further with it will be.

"islander says:February 20, 2012 at 21:49Totally disagree on “Ice-Quakes” this time or ANY OTHER TIME. Prepared bet my H&#250;fa on that. There are many “skri&#240;j&#246;klar” (crawling-glaciers) on edges on all the Icelandic Glaciers, but strange (looking at many EQ charts) they (EQ&#180;s) do not (regularily) appear where they (skri&#240;j&#246;klar) are! But people also often forget Icelandic Glaciers are NOT like the Glaciers in Greenland. Here they are with much lower density(?), not compact, more like compacted snow (grainy?) and have high wather content (Icelandic term is “&#222;&#237;&#240;j&#246;kull” against, near solid frosen ones in Greenland – Most of the time – but there is lots of water in Greeland Glaciers in summer season – even creating lakes in shallows, large enough for Catalina flying-boats to land on! It was done during WW-2.

No glacier(s) around Hekla for example. We have Glaciers at Tindfj&#246;ll, Torfaj&#246;kull, Myrdalsj&#246;kull and Eyjafjallaj&#246;kull.

Microseism ok. Problably due magma on (lateral?) move I think, rather than rising. Maybe its in more than one location, or alternatively flowing both east and north, from Katla, or some flowing away from Hekla?. Maybe Katla (and Hekla) is simply “full” and as “roof” does not “give way” it probably flows laterally thrugh old faults or channels."

"We can find dates of 871, 932, 1480, 1783, 1862. Calculating the repose intervals, there is an average of 247.75 years between events… but that is only four intervals and is statistically dubious at best. (it means that there is a lot of room for error)

However, it does also indicate that about 4.6 meters of crust expansion had occurred when the events happened. (low – 1.15 meters, high 10.3 meters), provided that my 18.8 mm/y. rate is valid that many years into the past… and it’s based on data from 2004 to the present. (pretty short sample period)

Anyway, that’s my take on it.

Right now we are at 2.8 meters of expansion since Trollagigar, 4.3 meters since Laki."

"Volcanic tremor (a low frequency vibration often caused by magma rising to the surface) has been observed under Katla volcano in southern Iceland, J&#243;n Fr&#237;mann reports on his Iceland volcanoes blo, closely following seismic activity in Iceland recorded both by national instruments and his own private geophone network. According to J&#243;n, there are 2 possible explanations: one could simply be an increase in hydrothermal activity in the northern part of Katla volcano. The second could be magma movements at depth although there have been no significant earthquakes that usually would accompany an intrusion or small (sub-glacial) eruption, although this still could occur in the near future as often observed in the past during similar episodes of tremor followed by earthquakes. The last minor eruption at Katla volcano was on 6 September 2011, and caused a small glacial flood"

IMO Islander it is closer to true.

That doesn't sound like good news to me. Moving laterally through old faults or channels. That could lead to fisure type eruptions. They don't know whats going on but lets hope they are wrong about this.
